+
+**Agent ID:** S2-H03
+**System:** Maintenance Log & Reminder System
+**Delivery Date:** 2024-11-13
+**Status:** COMPLETE
+
+---
+
+## Executive Summary
+
+The Maintenance Log & Reminder System is a comprehensive vessel maintenance tracking platform designed for the NaviDocs marine management ecosystem. The system provides intelligent reminder generation based on dual triggers (calendar date and engine hours), expense tracking, service provider integration, and calendar synchronization.
+
+**Key Capabilities:**
+- Track maintenance activities across 7 service categories
+- Dual-trigger reminder logic (date-based OR engine-hours-based, whichever comes first)
+- Automatic service provider recommendations from contact management system
+- Real-time expense rollup (YTD, annual, all-time)
+- Integrated calendar event generation and synchronization
+- Multi-channel notifications (push, email, SMS, in-app)
+
+---

+
+## System Architecture
+
+### Core Service Types
+The system tracks 7 distinct maintenance categories:
+1. **Engine** - Oil changes, impeller replacement, engine inspections
+2. **Electronics** - Autopilot, radio, navigation system maintenance
+3. **Hull** - Structural inspections, caulking, coating
+4. **Deck** - Hardware, fasteners, deck systems
+5. **Safety Equipment** - Life jackets, fire suppression, EPIRBs
+6. **Antifouling** - Bottom paint, haul-out, protective coating
+7. **Survey** - Professional marine surveys, certifications
+
+### Dual-Trigger Reminder Logic
+
+The system uniquely handles maintenance scheduling by supporting **both** calendar and engine-hours based reminders:
+
+```
+Maintenance Due When: next_due_date OR next_due_engine_hours
+Notification Trigger: Whichever comes first
+Example: "Oil change due every 100 hours OR 6 months"
+```
+
+This accommodates vessels with highly variable usage patterns where simple calendar-based reminders fail.
+
+### Five-Tier Notification Schedule
+
+| Days Before | Channels | Priority | Frequency |
+|---|---|---|---|
+| 60+ | In-app, Email | Low | Weekly |
+| 30-59 | In-app, Email, Push | Medium | Bi-weekly |
+| 14-29 | In-app, Email, Push, SMS | High | Weekly |
+| 7-13 | All channels | Urgent | Daily |
+| <0 | All channels | Critical | Daily |
